Abstract: Abstract of the Disclosure A mold used for making a sandwich-type construction block has a plurality of substantially flat walls defining a substantially closed parallepipedal cavity and each having an inner surface turned toward the cavity and a plurality of respective linings on at least some of the inner surfaces.  Each of the linings has a durable and flexible skin exposed in the cavity and a soft elastomeric layer at least 2mm thick lying between and adhered to the respective skin and inner face.  The mold is used by first removing, normally by pivoting out, at least one of the walls to open the respective side of the cavity.  Then at least two rigid tiles are fitted into the mold with the tiles spaced apart and the tile edges in snug engagement with the other walls of the mold.  A foamable synthetic-resin mixture is introduced into the space between the tiles fitted into the mold.  Finally the one wall of the mold is closed with concomitant compression of the respective lining to prevent the mixture from passing around the edges of the tiles.

Abstract: ABSTRACT OF THE DISCLOSURE   An improved base includes a base pad member having a flange plate attached to the bottom thereof for cooperation with a flat plate mounted on a post inserted in the ground.  The base plate may thus slide onto the ground plate in order to retain the base in position.  The base has a special oversized, generally rectangular construction so that a portion of the base projects beyond the first base foul line where it may be tagged by a runner.  The remainder of the base is positioned inside the foul line in the normal base position for tagging by a fielder.  The separate parts of the base are preferably denoted by distinctive color or design.  This configuration promotes safety.

Abstract: ABSTRACT OF THE DISCLOSURE:     A plate mould for continuous casting includes a carrying frame and broad-side walls supported therein and delimit-ing the mould cavity. Between the broad-side walls, end walls are arranged. The broad-side walls are adjustable normal to the axis of the mould cavity by an adjustment device and clampable relative to each other by a clamping device. In order to enable a perfect movement of the broad-side walls in the direction normal to the axis of the mould cavity, which is simple to maintain and adjust by the maintenance personnel, and to provide an easy in-stallation and removal of the mould insert, each broad-side wall is clampable in the vertical direction by at least one clamp strap, against a holding plate of the car-rying frame supporting the broad-side wall. The clamp strap is supported on the broad-side wall and on the car-rying frame and clampable against the carrying frame in the manner of a bending carrier by a tensioning device that is detachable from the upper side of the mould.

Abstract: Abstract of the disclosure:      The continuous process for digesting cellulose-containing material (substrate) is carried out by sorp-tion of gaseous HF in a sorption reactor (1) and subse-quent desorption in n steps, which are carried out in n reactors which are separated from one another in a gas-tight manner.  The substrate is introduced via a gas-tight valve into the sorption reactor (1), passes through this and then reaches consecutively, through gas-tight valves, a hold-up reactor (2) and the first (3c), second (3b),  ... nth desorption reactor, from which it is then removed.  The desorption is carried out in each case by the action of one of the n inert gas streams on the substrate at different temperatures, the particular inert gas stream be-ing enriched with the HF being liberated during desorption.          The gas streams, which are enriched to different extents with HF, are allowed to act on the substrate in the sorp-tion reactor (1) in such a manner that the gas streams of low HF concentration act on a substrate having a zero or low concentration of HF and thereafter the gas streams of higher HF concentration act on substrate having higher HF concentration.  The total gas stream (8a) produced from the individual gas streams leaves, after completion of sorption, the sorption reactor (1) largely freed of HF and is either conveyed to the desorption steps after dividing up into individual gas streams or it initially passes through the last desorption step (3a) and is thereafter divided up and passed to the other desorption steps in order, after passing through the latter, to be returned to the sorption reactor (1).

Abstract: IMPROVED COMMUNICATIONS INTERFACE                Abstract of the Disclosure A data link controller and an interface specification for network  interface modems  is  disclosed.   A specific modem is described for a client data processing unit for use in a broadband local area data network with collision avoidance   protocol.      The   controller   immediately acknowledges   receipt   of   a   perfect   data   packet independently of the processing unit without going through a line acquisition protocol.  Each received acknowledgment packet is placed in a transmit buffer at a known location relative to the data packet which was just transmitted, for  which  it   is  an  acknowledgment  so  that  each acknowledgment packet may be located in less time by the processing unit.  Also disclosed is an improved modem for a  single  frequency,  modulated  RF  carrier  local  data network  for a  distributed  data processing system and  a method  for  line  acquisition  and  contention  resolution. The  protocol  in  this  method  is  implemented by a modem controller which causes the receiver section to listen for interference beating,  i.e.,  changes  in amplitude on the line which indicates another unit is requesting the line, to determine when the line is busy.   If a contention is found,  it  is  resolved  using  a random delay  and retry protocol.

Abstract: ABSTRACT OF THE DISCLOSURE       An information while drilling apparatus and method for characterizing strata in the vicinity of a drill bit at the lower end of a drill string, includ-ing a down-hole module unit and surface receiving and control units.  Excitation currents are caused to pass through the drill string, drill bit and surround-ing strata and the current flowing through the drill bit is sensed by a first toroidal transformer that encircles the drill string immediately above the drill bit.  The sensed current, which is characteristic of the strata adjacent to and below the drill bit, is detected to form logging signals.  A second toroidal transformer couples the logging signals to the electrically conductive drill string for transmission to the surface receiving unit.  The frequency of the excitation current is adjustable to permit character-ization of the strata at various distances from the drill bit.  The frequency of the transmitting signal is also adjustable to compensate for varying degrees of signal attenuation along the transmission path. Control of the excitation and transmission frequencies is effected by communications from the surface control unit in response to stored operating instructions or operator inputs.

Abstract: ABSTRACT OF THE DISCLOSURE    For the purification of hydrocarbon-containing, e.g., methane raw gases containing H2S and CO2, the raw gas is dried, and separated by rectification into a hydrocarbon-rich overhead fraction containing some H2S and CO2 and into a bottom fraction consisting essen-tially of H2S and CO2.  The overhead product is freed, in a first scrubbing column, of the acidic components with a physical acting scrubbing medium selective for H2S and COS as against CO2, e.g., polyethylene glycol ether or toluene. The bottom product from the rectifi-cation step is vaporized and selectively desulfurized in a second scrubbing column with the same scrubbing medium, and the scrubbed gas from the second scrubbing column is discharged as CO2 under pressure.

The terminal includes a microprocessor coupled to a volatile memory and to first and second nonvolatile memories.  A first set of instructional signals stored in the first nonvolatile memory con-trols the microprocessor so that communication with a host com-puter can be established.  The host computer transmits to the terminal emulation data which is stored in the second nonvolatile memory as a second set of instruction signals.  Thereafter, in order to communicate with another data processing unit, the microprocessor of the terminal is controlled by the second set of instruction signals.
